3 Claims.

This invention relates generally to yarn treating apparatus and more particularly to improved spindles used in such apparatus.

It is the custom in the textile industry to treat the yarn or the like while it is in package form, such packages taking the form of a perforated tube, spool, cone or the like with yarn wound therearound. Such perforated tube or the like is usually slid over a perforated spindle which is secured to the wall of a drum or tank containing the liquid used, such as dye liquor or other liquids used for treating yarn, such as for bleaching and treating with resins. Heretofore the spindle on which the yarn is supported had a cap member or the like screwed onto one end of it to hold the yarn tube in place on the sleeve and spindle as well as to close the end of the spindle. Mounting this cap member on the spindle and demounting it takes time and is laborious and furthermore such cap member is liable to be dropped or forced off the end of the spindle and sleeve and liable to become loose allowing leakage of the dye or other liquor. It is also liable to become misplaced when removed.

It is an object of this invention to provide a spindle with simple means for effectively holding the yarn on its sleeve and spindle, and for effectively blocking the open end of the spindle to prevent leakage of the liquor.

It is a further object to prevent the possibility of the yarn holding and blocking device becoming separated from the spindle.

Another object is to provide a securing device which can be more quickly brought into action.

Another object is to provide a spindle from which the yarn may be more quickly removed.

In the drawing, Fig. 1 is a side view of a dye liquid holding tank or tube carrier with improved spindles mounted thereon, parts of the tank being broken away and shown in section.

Fig. 2 is a side view of the improved spindle with a perforated sleeve thereon shown in section.

Fig. 3 is a longitudinal sectional view of the spindle.

Fig. 4 is an end view of the spindle without the plug.

The treating unit includes a metal tank or carrier member ID for receiving the liquid. This tank is adapted to support or carry a plurality of packages I2 of material such as yarn, warp, rayon and the like shown dotted. While only four of such packages are shown, it will be understood that in practice such tanks are sufiiciently large to support and carry many more.

Each package includes yarn or the like wound on a suitable perforated sleeve I4 formed of a relatively rigid material such as hard fibre. The improved spindle I5 comprises a metal tubular body portion I6 formed with perforations I1 for substantially its length. Each end portion I8 and I9 of the body is enlarged. The sleeve I4 with its yarn is slid over the spindle I5 and supported on the enlarged ends I8 and I9.

The spindle end I8 is provided with a groove 2|] in its inner face which is adapted to receive the inner end edge of sleeve I4 and guide and interlock it on the spindle. The spindle has a screw threaded extension 2I which is adapted to be screwed into a threaded opening 22 in the tank II]. The spindle also preferably has a nutlike portion 23 to accommodate a wrench.

The spindle end I9 is formed with an inner enlarged bore portion with a wall 24 tapering toward the end as viewed in Fig. 3. The wall 24 of the enlarged bore is provided with a number of slits 25 extending from the outer edge to a point inwardly thereof as shown in Fig. 2 so as to form resilient jaws.

Movably mounted in the bore portion is a wedge-shaped or tapered metal plug 26 having a knob or handle 21 extending outside of the bore. Plug 29 fits slidably in the bore, and the tapers of the bore and the plug correspond to each other so that as the plug slides outwardly it tends to spread or expand the slitted end portion I9 into the sleeve I4 and tightly closes the bore. This expansion of the end I9 holds the sleeve on the spindle and also holds the skein of yarn in position on the sleeve and spindle and the tight engagement of the plug with the wall of the bore prevents any leakage of the treating liquid.

The enlarged and portions of the spindle hold the sleeve I4 away from the perforated portion of the body of the spindle permitting the dye liquor to pass through the perforations in the spindle and circulate between the sleeve and spindle and then pass out through the perforations in the sleeve.

To remove the sleeve I4 with its yarn, the plug 26 is forced inwardly by the hand of the operator.

In practice, the tank or carrier In with its supported spindles and packages is placed in a cylindrical enclosure having a perforated wall, which enclosure is placed in a vat. The liquid is pumped into the tank I0 under a pressure of approximate- 1y 35 pounds per square inch and forced through the bores of the spindles I5 and out through the perforations in the sleeves I4 into and through the yarn l2 impregnating said yarn. The excess liquor passes through the perforations of the cylinder into the vat and may be used over again. The pressure may be suflicient to seat the plug 26 securely in the spindle and prevent escape of liquid from the end of the spindle.

I claim:

1. An improved spindle for yarn treating apparatus including a perforated tubular body portion with screw threaded means at one end for securing it to a carrier and having the bore at the opposite end tapered with its smaller diameter outermost and slitted to provide expandable jaws at said end and a plug slidable in said slitted end, said plug being tapered with its inner end larger than its outer end for closing said slitted end and expanding said jaws within a yarn-supporting sleeve mounted on the spindle whereby said sleeve is held thereon to at least some extent by fluid pressure within the spindle exerted on the slidable plug.

2. A yarn treating spindle including a body portion perforated between enlarged substantially alined and parallel end surfaces, the inner end of the spindle having an extension for attachment of the spindle to a support, the opposite enlarged end having a tapered bore with its smaller diameter outermost, a perforate sleeve supported on the enlarged end surfaces of said spindle, the outer enlarged end of said spindle being slit and expandable, a plug tapered similarly to the taper of said bore and adapted when pulled outwardly to expand the slitted end of said spindle within the end of said sleeve, said plug being adapted to be pushed inwardly to allow the end of the spindle to contract and release the sleeve.

3. A yarn treating spindle having a central bore and comprising a body portion provided with perforations and end portions for supporting a perforate sleeve radially spaced from the spindle intermediate its sleeve supporting end portions, a threaded extension at one end portion for attaching said spindle to a support, an opposite end portion having its bore beneath the sleeve support tapered with the smaller diameter at the outer end, a plug having substantially the same taper as the bore, the tapered end part of the spindle having slits which are closed by the sleeve but which enable the tapered and slit end of the spindle to be expansible outwardly by pulling said plug outwardly and forcing the spindle into tight cooperation with the sleeve whereby the greater the fluid pressure in the spindle bore the stronger will the plug be forced outwardly and the stronger will the spindle end be pressed against the sleeve.
